Weel guys just did my 30,000 mile overhaul Changed everything to Royal purple products, gears, diffs, tranny, x-case, and engine. Everything Runs great so far and i am really impressed. I commute everyday about 2 hours so i do alot of driving and have gotten to know the truck well. Usually have really firm shifts that you can feel, well with the new stuff everything is alot smoother, runs quiter smoother shifts(barely feel them) yet i can tell it's shifting quicker. I know it's normaly expensive but my Dad owns a Reapir shop so we get it at the same price as Amsoil so decided to give it a try. So far i'm a beleiver

 

i have the royal purple in my engine and axles so far. i have noticed a slight improovment in power. and the max gear oil is $3 a quart cheaper than mopar oil.
